Romans 2:25-29

25Circumcision benefits you if you observe the law, but if you are a lawbreaker, your circumcision has become uncircumcision.

26So if an uncircumcised man keeps the law’s requirements, will not his uncircumcision be counted as circumcision?

27A man who is physically uncircumcised, but who keeps the law, will judge you who are a lawbreaker in spite of having the letter of the law and circumcision.

28For a person is not a Jew who is one outwardly, and true circumcision is not something visible in the flesh.

29On the contrary, a person is a Jew who is one inwardly, and circumcision is of the heart — by the Spirit, not the letter. That person’s praise is not from people but from God.
